I want to resize my apng file, but I need help.

[dogemad]

this is my codes.

const sharp = require('sharp');
const fs = require('fs/promises');

async function start() {
  const src = await fs.readFile('./src/0023ac17-e520-4ae4-9308-500608d5fad8.png'); // apng file

  const sample = await sharp(src, { animated: true })
    .resize({ width: 320, height: 320, fit: 'fill', fastShrinkOnLoad: false })
    .toFile('./dist/0023ac17-e520-4ae4-9308-500608d5fad8.png'); // only resized first frame, like thumbnail...
}

start();

What I expected is that the apng file is saved with only the size changed.
However, only the first frame was saved with the changed size. How do I resize and save all frames?
